The increased height of the MS79 knob means that the shifter is positioned closer to the steering wheel. This allows the driver to make quicker shifts and focus more on steering input. Machined from nylon 6/6 material, the MS97 Spec Shifter Knob is precision made to easily install (pressure fit, no screws) on your BMW's OEM shifter rod. Because it is made of nylon rather than aluminum or leather, this shifter knob also helps to reduce the transferred heat from the transmission. The elegant black design looks both functional and aggressive.
